To all whom itmay concern:

. Be it known that I, LEWIS D. HYATT, a citizen of the United States, residing at St. Louis, in the county of St. Louis City and State oi Missouri, have invented new and useful improvements in Sleds, of which the following is a speciiication.

My invention relates to sleds 4and more particularly to that type of sled having two sets of runners. It has been the common practice in such sleds to pivot the front set of runners and to guide the sled by turning this iront set of runners by any' suitable means, such as a cord or by pressure applied to the foot rest.

lt is the. object of the present invention tb provide means whereby such a sled may be much more perfectly controlled and more readily guided and to this end I provide a sled having two pivoted bogie trucks or sets of runners together with means for turning each set.

. With the above and other objects in view, the invention consists in the arrangement and construction oi' parts hereinafter described and shown in uthe accompanying drawings, in which,

Figure 1 is a side elevation oi my im roved sled. Fig. 2 is a central longitudine vertical section. Fig, 3 is a plan view of the same with body removed, and Fig. 4 is a transverse central section through the front truck.

Referring to the drawings in detail, 1 represents the body of the sled which may be of any suitable construction. Underneath this body is arranged a rear set of runners 2 and a iront set 3, the two sets being so located that there is ample space left between them for turning.

Secured to the under side of the body 1 by means of struts 5 and 7 are two circular frames 4 and c which I shall hereinafter refer to as Uliith wheels.

The runners of each set are secured together by the usual cross braces 8. Between the tops of the front and rear sets of runners extend holsters 9 and 11 and to these loolsters are rigidly secured vertical spindles 15 and 12, respectively. loosely through the fifth wheel 4 and is journaled at its'top in lthe body 1. The s indle 15 passes loosely up through fifth W eel 6 being connected by a sprocket chain 21.

The spindle 12 passesy and is journaled in a sleeve 1.7 which surrounds it and which in turn is lfreely journaled in the body" 1. Passing through the holsters 9 and 11 longitudinally are axles 14 and 13, respectively, which are 'free to turn in said bolsters, but the ends of which are rigidly secured into the upper parts or each set of runners. lt is, therefore, seen that the runners may rock longitudinally up and down, the axles 14 and 13 turning within the bolsters 9 and 11.

On the top of the spindle 15 'is mounted a hand wheel 16 and on top of the `sleeve 17 is mounted a hand. wheel 18. To the sleeve 17 -underneath the body is secured a sprocket wheel 19 and to the spindle 12 underneath the body is secured in the same plane, a

sprocket wheel 20, these two sprocket wheels It will, therefore, be seen that the l'ront truck I or set of runners 3 can beaturned bymeans of the hand wheel 16 directly connected thereto by means 'of the spindle 15, while the rear truck or set of runners 2 can be turned on the spindle 12 by n'eans of the hand wheel 18 connected therewith through the agency of the sleeve 17, sprocket wheels 19 and 20 and sprocket chain 21. The hand wheels 1G and 18 are arranged in parallel planes a short dis* tance apart so that either one may be manip- .ulated` independently of the other or il desired both may be moved together. The axles 13 and 14 constitute horizontal pivots about which the runners may be turned in going over uneven places and may thus adapt themselves to the variation of the ground over which they are traveling.'

It will thus be seen that l have provided a very flexible and convenient car for sleds and the like, and it is'thought the numerous advantages of my invention will be readily appreciated by those skilled in the art.

lhat l claim is:

1. ln a vehicle, a frame or body, front and rear bogie trucks pivoted thereto, hand wheel connected with said front truck, and a concentric hand wheel connected with said rear truck whereby each truck may be guided independently.

2. In a vehicle, a frame or body, front and rear bogie trucks, avf-rtical shalt connected to said front'truck and carrying a hand wheel at its upper end, a sleeve surrounding said l shaft and also carrying a hand Wheel at its l as rocket Wheel carried by the outer sleeye, 10 v upperv end, and means connecting said sleeve. Wit-h said rear truck. v

3. In a vehicle, a frame or body, front and rear bogie trucks, a vertical shaft connected an a' sprocket chain connecting the two sprocket Wheels.

l In testimony whereof, I aHiX my signature in presence of two witnesses.
